Developing Fuzzy Scheduling System for Jobs Prioritization & Route Selection of Jobs in FMS

In this study, we have done the scheduling of FMS using fuzzy logic approach. It has been applied by many researchers to various manufacturing problems. With the help of fuzzy logic, we can incorporate both numerical and linguistic variables. The advantage of fuzzy logic is that it has the ability to consider multiple criteria and can deal with uncertain or incomplete information. Scheduling of FMS is considered to be more arduous and complex than a conventional manufacturing system. Due to this, it is one of the arduous tasks to determine an optimal schedule and control a FMS environment. We have developed a fuzzy scheduling system using a fuzzy logic approach. This scheduling system will help in identifying job priorities and select the best alternative route with multi-criteria scheduling through fuzzy logic approach in Matlab. There are three inputs for both job priorities and route selection and this inputs are further divided into three ranges so total 27 rules will be used in fuzzy logic. With the help of these rules, the job selection and route selection both will be done.
